OIL-FEEDER ron mrnmmn-comnusrron ENGINES.

To all whom it may concern Be it known that I, ELI TEETER, a citizen of the United States, and resident of Jersey City, in the county of Hudson and State of- New Jersey, have invented certain new and useful Improvements in Oil-Feeds for Internal-Combustion Engines, of which the following is a specification.

This invention relates to a device for feed-.

ing oil under pressure and discharging it in atomized condition into the ignition champarticularly to a device of this kind adapted to feed the heavier distillates of petroleum. The object of the invention is to provide atomizing discharge which may be regulated at will, and to these ends consists in providing a discharge nozzle having its bore or outlet partially closed by a plugwhich enforces spreading of the fuel and at the same time divides up the spray by compelling it to escape through surface grooves at the pethe dischargee'nd being riphery of the plug; preferably flared and the entering portion of the plug correspondingly tapered.

In the accompanying drawing, Figure 1 is an axial section of an oil feed device to WhlCh my invention is applied; Fig. 2 is anenlarged detail view of the nozzle detached from the oil feeding device and seen from above; Fig. 3 is an axial section of the nozzle with the spraying plug removed; Figs. j

land 5 are respectively a side and an end view of the spraying plug.

Referring toFig. 1, 1 represents an inlet to which oil is fed under pressure from a suitable external source. 2 is a return bypass adapted to be closed by needle valve 3,

v and 4 is a feed duct controlled by a check valve 5 through which the oil is forced. when the by-pass 2 is closed. 6 represents the nozzle relates see Figs. 2 and 3. This nozzle is constructed with a threaded shank 1,3", screwed mto a corresponding socket in the valve body. The plug 9 Figs. 4 and 5 which is secured in place by 1ts threaded shank 1,2 entering the correspondingly,

to which my present invention.

threaded socket in the nozzle 6*, is provided witha knurled head 10 which has grooves for the escape of the oil and a central bore M which feeds the symmetrically disposed radial ports 14: by which the fuel is delivered to the flaring p rt of the outlet 7 in the nozzle plug 6 T e bore 7 of the plug Patented May a, 1915.-

6 terminates in a cylindrical portion 7 'oruin other words in atomized condition,

which adapts it "to mingle thoroughly with theco'ntained air or air and other medium in the combustion chamber. By regulating the position, of the screw-threaded plug in v the bore of'the nozzle, the resistance to discharge and, consequently, the degree of atomiz'ing may be regulated at will to a nicety.

An oil feed for internal combustion engines "comprising. a pressure actuated fuel feed and a nozzle suppIied thereby; said nozzlebeing constructed with a bore having a tapered portion and a cylindrical portion beyond the tapered portion, and a plug constructed with a tapered portion conforming substantially to the tapered portion of the bore and with a substantially cylindrical tion of the bore; said plugbeing adjustable in said bore. p I
